Improvement in sash-holders



ennuh trir5 'am esta@ Lettersl Patent No. 108,968, dated November 8, 1870.

IM PROl/EMEN'T IN SASl-l-HOLDERS.

The Schedule referred to in these Letters Patent and making part of the same.

,is designed to be attached to the surface of the windowcasing and sash without requiring any mortising for the purpose.

My improved lock consists of a met-allie socket for attachment to the window-easing in relief, provided with inclined surfaces or ways to guide the ends of a spring or automatic .locking-catch or bolt into the socket as it approaches the latter, in either direction, during an upward or adownward movementof the sash, y

and of an automatic locking-armor catch, pivoted and secured wlth a coiled spring in a cap-bearing plate,

which is fastened to the surface of thersash, the' parts being constructed and arranged as hereinafter fully' shown and described.

In the accompanying drawing- Figure I is an elevation of the spring-arm as .attaehedto the sash, shown'engaged with socket-plate, which is represented in vertical section, secured in place to the window-casing.

Figure II is a-vertical section oi' the side bar of the sash, showing the manner of securing the spring-arm and cap-bearing plate thereto.

vFigures III and IV, a side and face View of the inetallic socket. A

Figure V is a planet' the back or inner face of the bearing-plate or cap.

Figure VI is a view of the interior of the cap, showing the coiled spring, and stop east with the former for securing the end of the latter in place.

Figure VII is a similar view, with the addition of the arm-catch arranged in the position for compressing the spring in place by means of a shoulder cast with the arm, which retains one end of the spring.

Figure VIII is a view similar to the last, with the parts arranged in their proper and operative position.

Figure IX is an inner face view of the'arm-catch, showing the shoulder thereon, beyond which one ot thc ends ofthe spring is secured.

- Figure Xv is a section of the spriug-arm and its bearing-plate v Like letters of reference designate like parts in each of the igurcs.

A is a portion of the window-casing.

B, a portion of the window-sash.

C, metallic socket, represented iastened to thc easing by two screws, h h., with its face formed by two inclines, c c, which project outwardly and toward the center, where the h'ole or socket c'is made, as shown in Figs. I, III, and IV.

D is an arm-catch, provided with a locking projection, d, which fits in the socket-hole c', and a thumbpiece, all, by which itis disengaged or released therefrom. Its inner end is made of circular form, so `as to rit and turn in"the circular depression in the cap or bearing-plate.

lhe inner face of this end of the arm is also formed with a shoulder, d2, and its edge with a notch, (Z3.

E is the cap or bearing-platecast with a depression or pocket, e, to receive the rounded end of the arm, which vsocket or depression is left open at one end, or provided with a recess, as, shown at el, Figs. VI, VII, and VIII, for the arm D to tit and work in.

The base of this circular depression is also formed with .a stop or spur, e2, which serves to retain one end of the spiral or coiled springt', that rests against it, as shown in Fig. VI, in which the spring is represented as arranged around a rivet, ln, inserted through a hole iu the cap, which serres as a guide or bearing for the spring. Ihe spring being in the position shown in this figure, the arm D is applied thereto, with the shoulder d2 in contact with the end of the spring opposite the stop c2, as represented in Fig. VII. By turning the arln in the direction ot' thearrow in the latter figure, thc shoulder Z2 compresses the end of the spring iu contact therewith, until it is made to assume the position shown in Fig. VIII, in which the ends ofthe spring are represented retained in place between and by the stop and shoulder c2 d2, the arm projecting Vthrough the open side or-notch el of the cap, and the stop cgup in the notch ll in the edge of the arm. j

.'Ihesc parts being arranged as described, a' disk 0r plate, S, iitting in and resting on a shoulder or ledge, r, around the edge of the circular recess or socket of thc cap, forms a washer and cover, through which the end ot' the rivet passes, and ,is riveted, as shown in- Fig. X, securing the end of the arm D in place between t yis washer and the base ofthe cap.

The p ate or washer S extends outward in the recess e', iiush with-the edge ofthe cap, as shown ats,-

whereby it is prevented from turning on its seat.

The bearing Ior cap E is secured to the sash by means of a ange, u, on vthe side opposite the notch cl, through which a screw', in, is inserted into .the y wood.

To prevent this cap or bearing from turning, a pin -or spur, s', cast with the washer-plate at the side opposite the flange u, is driven or inserted in the sash,

which enables a single screw to properly secure thev device in place.

My improved fastening being constructed and put together as hereinbefore described, and arranged with the sash and casing as shown in Fig. I, its operation becomes obvious. The sash in this figure, which is shown locked down, is released by withdrawing the spring-catch D, as represented by dotted-lines. The socket-plates C beingr attached to the easing at intervals, the raising or lowering of the sash causes the catch il to slide up or down the inclines c until it reaches the socket c', into which it is automatically forced by the action of the spring i, whether the sashis being raised or lowered.

The notch el, in the cap or bearing E, forms a stop for lthe arm, so as to prevent the catch d from coming in contact with and wearing the casing between the sockets as lthe sash is raised and lowered.

My improved fastening can be cheaply made by casting the parts complete, can be easily applied without mortising either the sash or casing, and forms a reliable fastening, certain in its operation, and, being exposed to View, the accidental falling of the sash and. breaking of the glass, which so frequently occurs when the locking parts are concealed, are avoided.

NVhat I claim is- 1. The hinged springarm D, provided with hooked catch d and thumb-piece (l, and arranged to operate in combination with a doubly-inclined socket-plate, C, as hereinbefore specified.

2. The cap-plate E, provided with stop e2, arranged with the spring i, rivet n, and arm D, provided with shoulder (l2, substantially as and for the purpose here inbefore Set forth.

3. The notch d in the arm D, arranged with the projection e2 in the cap-plate E, as' and for the purpose hereinbefore Setforth.

4. The cover or washer S, provided with extension s and spur s', arranged with the cap-plate E, provided with recess e* and ilange u, as and for the purpose hereinbeibre described.
